clock: hrtimer: Add workaround to fix building error about hrtimer based broadcast on PowerPC

The hrtimer broad support was back-ported from upstream for LS1, the Power
 platform do not implement this yet. The tick_setup_hrtimer_broadcast
 function was not defined on Power platform.

When build for PowerPC with this backport support, such error occurs:
In file included from include/linux/tick.h:9:0,
                 from arch/powerpc/kernel/idle.c:27:
include/linux/clockchips.h:193:13: error: 'tick_setup_hrtimer_broadcast'
defined but not used [-Werror=unused-function]

As hrtimer based broadcast was only backported for ARM, this patch try to
provide a workaround to fix the build error on Power platform.

In linux-next, PowerPC will support hrtimer based broadcast too. There will
be no build error and no workaround needed.
